The Arctic ice is melting faster and faster, but now a research team thinks it has found a solution: artificial islands, huge pumps and underwater dams must stop melting.
The ice in the North Pole is melting at an alarming rate. That is why a research team from the University of Lapland in Finland has come up with technical projects to prevent glaciers from sliding into the sea and melting.
The researchers used the glacier at Pine Island in western Antarctica as an example. It slides away at a speed of 4 kilometers per year.
On the coast he loses his grip on the bottom, after which he goes out onto the sea like a big ice floe. He then begins to melt, and the researchers now want to stop that.
Three measures keep the ice cold
Several projects are meant to protect and stabilize the ice floe and curb the movement of the glacier.
The ideas range from pumping stations that have to pump the water layer under the glacier to submarine dams that prevent warm sea currents from coming into contact with the ice floes.
Expensive but necessary
According to the researchers, the projects only have to be implemented on a few routes along Antarctica and Greenland for a noticeable effect.
For example, 90 percent of the ice movement towards the coast of Antarctica runs via ice currents that are less than 100 kilometers wide. The same applies to 50 percent of ice migration on Greenland.
The scientists realize that the implementation of projects will be in the papers, but think that the costs outweigh what the world loses if we do nothing. According to various forecasts, the water level of the sea will have risen by 0.5 to 2 meters by the year 2100.
Dam must cool the ice
An underwater dam must ensure that the water around the ice remains cold. At the same time, the movement of the ice towards the sea is slowed down by an artificial island and by drilling.
